A hinge manufacturing company employs a Kanban system for a component part. The daily demand is 900 hinges. Each container has a wait time of 0.05/day, and a processing time of 0.37 days. The container size is 60 hinges, and the safety factor (α) is 10%. Given this data, the number of Kanbans necessary for this system is _____.
A) less than 4 Kanbans
B) more than 4 but less than or equal to 8 Kanbans
C) more than 8 but less than or equal to 12 Kanbans
D) more than 12 but less than or equal to 16 Kanbans

First, we need to calculate the number of containers required to fulfill the daily demand:

Containers per day = (Daily demand + Safety stock) x (Wait time + Processing time)
= (900 + 10%) x (0.05 + 0.37)
= 990 x 0.42
= 415.8 ~ 416

Next, we need to calculate the number of Kanbans required:

Kanbans = Containers required / Container size
= 416 / 60
= 6.93 ~ 7

Therefore, we need 7 Kanbans for this system. Since the closest option is "more than 4 but less than or equal to 8," the answer is B.
